Playing CB Full as the Germans against the AI. I still don't quite get how supply works, particularly regarding either via rail or road or just open terrain. Wish I new how to show a screen shot. The Sovs have a sizable force clustered about 8 hexes west of Swatovo and Ravenku that they never retreated but are now trying to move east. In the south I captured the rail line running to Millerovo. I am postured to potentially capture the rail line leading up to Starobelsk. In the north I can advance if I choose and cut the rail lines nrunning through Usman and Svoboda respectively. Is there any value in this in terms of, if I capture these rail lines, really crimping Sov supply to those aforementioned units? Again apologize for the lack of screen shot which no doubt makes it hard to visualize this. In short, if I capture these rail lines, the Sov has absolutely no direct rail line to those units for supply purposes. Does this matter?

As a general rule of thumb, when playing against the AI it is a good idea to cut rail lines, the same for against human players, but they tend not to let you do it

On clear weather turns the Soviet units shouldnt have a problem getting supply if they still have an indirect road or rail route. But where they start to suffer is after mud turns. Firstly the supply is more difficult to get through on mud turns and secondly it then takes them a while to rebuild their supply stocks, especially if you can get them moving.

I tend to play fairly intuitively, so dont try and calculate supply in depth, but hopefully one of the more experienced players will come along and give a more in depth explanation.
